Preparation, Characterization and Performance of Polyethersulfone(PES) – Polyaniline(Pani) Blended Membrane

Abstract:

Polyaniline nanoparticle was synthesized via the chemical oxidation of aniline with ammonium persulphate in aqueous hydrochloric acid where the polyaniline particle size obtained was in the range of 22-53 nm. Polyaniline is one type of conducting polymers, where this polymer exhibit high electrical conductivity and have a wide range of interesting application due to its light weight, conductivity and chemical properties. Amongst the family of conducting polymers, polyaniline is unique due to ease of synthesis, environmental stability, simple doping/dedoping chemistry and relatively inexpensive cost. Polyaniline has been used to improve hydrophilic property and permeability of substrate membrane. It is used to obtain superhydrophilic surface because of their high surface energy and hydrophilic property. In this research, these nanoparticles have been used to improve hydrophilic property and permeability of polyethersulfone membrane. The blended membrane was characterized using pure water flux, Scanning Electron Microscope (SEM), and contact angle. As a result, polyaniline can distribute stably in polyaniline membrane to produce stable structure and preferable performance.
